MARIETTA, Ga. (AP) — A prosecutor in the trial of a man accused of killing a baby in a stroller in coastal Georgia says witnesses may have had shifting stories and occasionally lied. But he says video and other evidence doesn’t lie.

De’Marquise (deh-mahr-KEES’) Elkins is charged with murder in the March killing of 13-month-old Antonio Santiago in Brunswick. Elkins’ mother, Karimah, is on trial alongside him on charges of evidence tampering and lying to police.

Prosecutors say Elkins killed Antonio in an attempted robbery. The baby’s mother, Sherry West, was also shot. The trial is being held near Atlanta because of pretrial publicity.

Jackie Johnson, the Brunswick Judicial Circuit district attorney, said in her closing argument Friday that the only person whose story didn’t match with the evidence in the case was De’Marquise Elkins.
